COAST- D EFENSE.

SPECIFICATION forming part of Letters Patent No. 239,22, dated March 22,1881.

Application filed January 10, 1881. '(No model.)

all whom it may concern:

Beit known that I. THEononE R.'l`1MBY,a citizen ofthe United States,residing` at Nyack, in the countyof Rockland and State of New York, haveinvented Improvements in Coast- Defenses, of which the following is aspecifica- The subject of my invention is atower or turret mounted torevolve on a vertical axis on a bed or base, which latter is itselfcapable ot' rotation on a suitable foundation carrying the said tower orturret with it, so that it' the tower is set in an eccentric positionori Vthe Ievolving hase the revolution of the latter will carry thetower in an orbit around a center other than its own. v i

Tile invention further relates'to mounting a` revolving t'owefor turretou a revolving base in such a manner that the said turret may beadjusted radially on the revolving' base, so as to be set in eithereccentric or concentric position thereon.

ln order that the inv-entioninay he fully understood, l will proceed todescribe it with reference to the accompanying drawings, in whichllignre1 is a perspective view, showing; the tower in central position on thebase. Fig. 2 is a perspective view, showing' the tower in eccentricposition on the base. Fie'. 3 is a plan, also showing; the tower ineccentric position. Fig. 4 is a vertical section on the line/1 1, Eig".3.

l represents a bed or base capable of revolution on a vertical axis onasuitable foundation, A., and having' on its upper surface asuitableslot and ways (indicated at C) for the support and the adjustment to undl'roln the center ot' a tower or turret, l), which latter is alsocapable oi' rotation on a vertical axis independontly ol' the rotatingbase or bed l, by which it is supported and carried.

Adequate and suitable ineeininisin l'or iinparting the required rotationto the bed or base B and the towel-D on the said bed or base, and movingor adjusting the tower D to or from the center of the bed or base, arewithin the knowledge of mechanics, and do not require specificdescription. Screw gearing, racks, and pinions, or any suitablemechanical appliancesmay be used for these purposes.

'The ,tower or turret D is pierced with einbrasures el for enns of anysize or character. The revolving base or bed B may also constitu teaeasemate, being pierced with embrasures for guns, as shown at d.

,W'Froin'the above ldescription it will 'appear that the revolving,`tower orft-iirret Ik), when set in 'the center of the bedfor ibaseB.1mayderive its rotation from the rotation of the bed or base, or maybe rotated independently thereon,

aspreterred; but that when adjusted radially outward, as illustrated inFigs. 2, 3, and 4, the

nient of the revolving base orbed B on its.l

own axis, be carried bodily to another position, and thus reinovedoutot' the range of an en eniys guns after they have been trained upon itin the position first held.

Having thus described lmy invention, the following is what l claim asnew therein and desire to secure by Letters Patent:

l. A bed or base revolving ona vertical axis, in combination witha loweror turret mounted eccentrically thereon and revolving on a vertical axisother than that of the bed or base.

2. The combination of a revolving bed or base, and a tower or turretmounted thereon, and capable ot' independent rotation and radialadjustment, as shown.-
